Tropifexor plus cenicriviroc combination versus monotherapy in nonalcoholic steatohepatitis: Results from the phase 2b TANDEM study.

BACKGROUND AND AIMS: With distinct mechanisms of action, the combination of tropifexor (TXR) and cenicriviroc (CVC) may provide an effective treatment for NASH. This randomized, multicenter, double-blind, phase 2b study assessed the safety and efficacy of TXR and CVC combination, compared with respective monotherapies. APPROACH AND RESULTS: Patients (N = 193) were randomized 1:1:1:1 to once-daily TXR 140 µg (TXR 140 ), CVC 150 mg (CVC), TXR 140 µg + CVC 150 mg (TXR 140 + CVC), or TXR 90 µg + CVC 150 mg (TXR 90 + CVC) for 48 weeks. The primary and secondary end points were safety and histological improvement, respectively. Rates of adverse events (AEs) were similar across treatment groups. Pruritus was the most frequently experienced AE, with highest incidence in the TXR 140 group (40.0%). In TXR and combination groups, alanine aminotransferase (ALT) decreased from baseline to 48 weeks (geometric mean change: -21%, TXR 140 ; -16%, TXR 140 + CVC; -13%, TXR 90 + CVC; and +17%, CVC). Reductions in body weight observed at week 24 (mean changes from baseline: TXR 140 , -2.5 kg; TXR 140 + CVC, -1.7 kg; TXR 90 + CVC, -1.0 kg; and CVC, -0.1 kg) were sustained to week 48. At least 1-point improvement in fibrosis stage/steatohepatitis resolution without worsening of fibrosis was observed in 32.3%/25.8%, 31.6%/15.8%, 29.7%/13.5%, and 32.5%/22.5% of patients in the TXR 140 , CVC, TXR 140 + CVC, and TXR 90 + CVC groups, respectively. CONCLUSIONS: The safety profile of TXR + CVC combination was similar to respective monotherapies, with no new signals. TXR monotherapy showed sustained ALT and body weight decreases. No substantial incremental efficacy was observed with TXR + CVC combination on ALT, body weight, or in histological end points compared with monotherapy.

Efficacy and safety of everolimus with reduced tacrolimus in living-donor liver transplant recipients: 12-month results of a randomized multicenter study.

In a multicenter, open-label, study, 284 living-donor liver transplant patients were randomized at 30 ± 5 days posttransplant to start everolimus+reduced tacrolimus (EVR+rTAC) or continue standard tacrolimus (TAC Control). EVR+rTAC was non-inferior to TAC Control for the primary efficacy endpoint of treated BPAR, graft loss or death at 12 months posttransplant: difference -0.7% (90% CI -5.2%, 3.7%); P < .001 for non-inferiority. Treated BPAR occurred in 2.2% and 3.6% of patients, respectively. The key secondary endpoint, change in estimated glomerular filtration rate (eGFR) from randomization to month 12, achieved non-inferiority (P < .001 for non-inferiority), but not superiority and was similar between groups overall (mean -8.0 vs. -12.1 mL/min/1.73 m2 , P = .108), and in patients continuing randomized treatment (-8.0 vs. -13.3 mL/min/1.73 m2 , P = .046). In the EVR+rTAC and TAC control groups, study drug was discontinued in 15.5% and 17.6% of patients, adverse events with suspected relation to study drug occurred in 57.0% and 40.4%, and proteinuria ≥1 g/24 h in 9.3% and 0%, respectively. Everolimus did not negatively affect liver regeneration. At 12 months, hepatocellular recurrence was only seen in the standard TAC-treated patients (5/62; 8.1%). In conclusion, early introduction of EVR+rTAC was non-inferior to standard tacrolimus in terms of efficacy and renal function at 12 months, with hepatocellular carcinoma recurrence only in TAC Control patients.

A randomized, double-blind, multicenter, phase 2b study to evaluate the safety and efficacy of a combination of tropifexor and cenicriviroc in patients with nonalcoholic steatohepatitis and liver fibrosis: Study design of the TANDEM trial.

BACKGROUND: Nonalcoholic steatohepatitis (NASH) is a multifactorial disease involving different contributing mechanisms, with no approved therapies so far. Tropifexor (TXR), a farnesoid X receptor agonist, and cenicriviroc (CVC), a chemokine receptor types 2/5 antagonist, target the steatotic, inflammatory, and/or fibrotic pathways involved in NASH. DESIGN: TANDEM (CLJC242A2201J; NCT03517540) is a 48-week, phase 2b, randomized, double-blind, multicenter study in 200 adult patients with biopsy-proven NASH and liver fibrosis. Patients will be randomized in a 1:1:1:1 ratio to receive either TXR 140 µg once daily (qd), CVC 150 mg qd, TXR 140 µg + CVC 150 mg qd, or TXR 90 µg + CVC 150 mg qd. The study comprises a 48-week treatment period and 4 weeks of follow-up. The key inclusion criterion is presence of NASH with fibrosis stage F2/F3 as seen on screening liver biopsy or on historical liver biopsy performed within 6 months prior to screening. OBJECTIVES: The primary objective is evaluation of the safety and tolerability of combination therapy compared with the monotherapies over 48 weeks. The secondary objective is to evaluate efficacy as assessed by ≥1-point improvement in liver fibrosis versus baseline or resolution of steatohepatitis after 48 weeks. SUMMARY: TANDEM will evaluate the combination of TXR and CVC with respect to safety and efficacy outcomes related to improvement in fibrosis or resolution of steatohepatitis. Given the effects of TXR and CVC in multiple pathophysiological pathways associated with NASH, combination therapy is likely to show additional benefits compared with monotherapy.

Cardiovascular Parameters to 2 years After Kidney Transplantation Following Early Switch to Everolimus Without Calcineurin Inhibitor Therapy: An Analysis of the Randomized ELEVATE Study.

BACKGROUND: Mammalian target of rapamycin inhibitors may confer cardioprotective advantages, but clinical data are limited. METHODS: In the open-label ELEVATE trial, kidney transplant patients were randomized at 10 to 14 weeks after transplant to convert from calcineurin inhibitor (CNI) to everolimus or remain on standard CNI therapy. Prespecified end points included left ventricular mass index and, in a subpopulation of patients, arterial stiffness as measured by pulse wave velocity. RESULTS: The mean change in left ventricular mass index from randomization was similar with everolimus versus CNI (month 24, -4.37 g/m versus -5.26 g/m; mean difference, 0.89 [p = 0.392]). At month 24, left ventricular hypertrophy was present in 41.7% versus 37.7% of everolimus and CNI patients, respectively. Mean pulse wave velocity remained stable with both everolimus (mean change from randomization to month 12, -0.24 m/s; month 24, -0.03 m/s) and CNI (month 12, 0.11 m/s; month 24, 0.16 m/s). The change in mean ambulatory nighttime blood pressure from randomization showed a benefit for diastolic pressure at month 12 (P = 0.039) but not at month 24. Major adverse cardiac events occurred in 1.1% and 4.2% of everolimus-treated and CNI-treated patients, respectively, by month 12 (P = 0.018) and 2.3% (8/353) and 4.5% by month 24 (P = 0.145). CONCLUSIONS: Overall, these data do not suggest a clinically relevant effect on cardiac end points after early conversion from CNI to a CNI-free everolimus-based regimen.
